Question Reading from a file and inputting into a string array I am getting a errors.

[dpfaff]

Hello, I am relativly new to programing, and I need some help on a lab project. If anyone out there can explain why I am getting the following errors.

55: inlab was not declared in this scope
In funtion void selectionSort(char (*)[25], int)
74:error: Stropy was not declared in the scope
77:error: Stromp was not declared in the scope
77: expected ';' before ) token

The Lab Assignment was to write a program so that the user reads 6 words or names into an array from a file. The unsorted array is then printed out on the screen.
Then using the Selection Sort for these words/names, they are sorted and the sorted array is printed out on the screen.

Below is the code I have written, How can I fix these errors. Any kind of help with this would mean a world of diffence. Thanx in advance.

You wrote these out didn't you, rather than copy and paste them?

If you transcribe this stuff by hand, you're just going to add to the errors which are already there, and make it harder for us to figure out your problems.

> Strcpy(minValue, array[start]);
> if (Strcmp(array[index], minValue) < 0))
See, these are the actual calls, with a 'c' and not an 'o'

In any event, it's strcpy and strcmp, ie, all lower case.

In future, use [code]
[/code] tags for large blocks of code. [icode]
[/icode] is meant for single lines embedded in normal text.

[dpfaff]

You are correct, however I did use the 'c' and not the 'o' for the calls. So I don't think that is the problem here. Thanks checking it out though.

[Salem]

So did fixing the case of initial letter fix the problem?

[dpfaff]

No, I still have the errors I'm not sure why, I double checked it and I belive they are all in the proper case. check it out
